11. The apparatus of claim 7 , wherein the resource allocation information includes at least one of a Downlink Interval Usage Code (DIUC) indicating a number of slots each MS will receive and a location of a related slot, information related to a Repetition Coding, information related to a Power Boosting, an Identifier (ID) of a zone, a Start Offset indicating a starting point of frequency resource related to the zone, and a Length indicating a length of frequency resource related to the zone.
12. The apparatus of claim 7 , wherein the resource allocation information includes at least one of a start offset and a length for the allocated frequency resource.
13. The apparatus of claim 7 , wherein resource slots in the frequency resource available for each zone are indexed in a round-robin order.
14. A method for receiving allocated frequency resources by a Mobile Station (MS) in a frequency overlay system, the method comprising: receiving zone information indicating a frequency resource available for each zone from a Base Station (BS); receiving resource allocation information indicating an allocated frequency resource, which is unicast to at least one MS to which the frequency resource is allocated, among a plurality of MSs which are grouped based on zones; and communicating with the BS using the allocated frequency resource indicated by the resource allocation information, within the frequency resource indicated by the zone information, wherein the BS groups the plurality of MSs based on the zones, each zone including a plurality of MSs capable of using a same frequency set, and wherein at least one Frequency Allocation (FA) of a frequency set related to one zone overlaps with at least one FA of a frequency set related to another zone.
15. The method of claim 14 , wherein the zone information indicates a starting point of resource slots in each FA included in a frequency set available by the MSs which belong to the related zone.
